Abstract

Background The purpose of this study was to use artery grafts filled with CACIPLIQ20 and see if they promote nerve regeneration.

Methods Sixty male Wistar rats were used. The rats were randomly divided into four experimental groups (n = 15): transected control group (negative control group [NCG]), sham-operated group (positive control group [SO]) artery graft group filled with saline (AG/NS), and CACIPLIQ20-treated group (AG/CACIPLIQ20). Fifteen rats were used as artery graft donors. In the SO group, the sciatic nerve was dissected from the surrounding tissues and left intact. In the NCG, AG/NS and AG/CACIPLIQ20) groups, a 10-mm gap was created in the left sciatic nerve. In the NCG group, the gap was not bridged with a graft. In the AG/NS group, the gap was bridged with a graft filled with saline. In the AG/CACIPLIQ20 group, the graft was filled with CACIPLIQ20. Walking track analysis was performed at 4, 8, 12, and 16 weeks after surgery. At 16 weeks postoperatively, the rats were sacrificed, nerve sections were harvested for histopathology analysis, and the weight ratio of the gastrocnemius muscle was measured.

Results There was no significant difference in myelin sheath thickness between the AG/NS and AG/CACIPLIQ20 groups. Muscle weight in the AG/CACIPLIQ20 group was higher but not statistically significant (p = 0.168) compared with the AG/NS group. Also, AG/CACIPLIQ20 mean was better than AG/NS mean, although there was no statistically significant difference (p = 0.605).

Conclusion There could be an indication that CACIPLIQ20 improves functional recovery of a transected peripheral nerve through a nerve gap bridged with an artery graft.
